Application filed May 20,

T 0 all whom it may concern.

Be it known that I, ALBERT W. METZNER, a citizen of the United States, and a resident of the city of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Printing Presses, of which the following is a full, clear, and exact description, reference .being had to the accompanying drawings, forming a part of this specification.

My invention relates to the provision of a cancelling device to be employed with numbering machines.

In the machines now employed for numbering a succession of forms in long strips of paper, it is necessary atvtimes to leave a few forms unnumbered, so as to permit the operative who rolls iip or binds the forms,

to make a break between one binder or roll and the next, while preserving successive numbers for the binders or rolls of a series.

In the numbering of the forms in autographic register paper, for example, which is sold in rolls, it is desirable to have say, five hundred forms on each roll, and to have each roll end and the next roll begin with successive numbers The paper in autographic register practice is usually run the width of say three strips to form an original and two duplicates, and to form a break of sufficient width to allow for tearing and trimming, it. is good practice to leave ten forms or. there-abouts for each five hundred or 1whatever number is mounted on each rol To do this in the presses of today results simply in several of the forms being without numbers. and if the operator of the numbaring ,press fails to mark Ofi each form that is unnumbered with his pencil, and fails to keep accurate tab on his press so as to leave un-numbered the forms which should properly be left blank, trouble is sure to occur. In the first instance the workmen who cut and roll the paper, are likely to get n unnumbered form on a roll, and in the second instance, the number of forms to a roll will not be uniform.

Not only this, but it is quite a diflicult op- It is the object of my invention, therefore, to provide a device which 1n combination 1920. Serial No. 382,879.

withanumbering press head, will operate to throw out the numbering devices from operation for a given number of strokes at determined intervals of the pre'ssoperation. It is further my obiect to provide a device which will print the word Void or some similar word, whenever the numbering device is thrown out of operation.

. The above objects and other advantages to be noted I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 is a. side elevation of the device of my invention.

Figure 2 is a top plan view of the same. Figure 3 is a detail section showing one method of lowering the Void printing bar.

Figure 4 is a diagrammatic view illustrating the shaft and eccentrics of the dev1ce. Figure 5 is a plan view of a modified form of cam controlling gear wherein by means of a number of tooth plates the speed of revglution of the wheel is greatly accelerate A Figure 6 is a detail perspective of the device for preventing the operation of the operating device for the cam controlling gear. In an endeavor to simplify the showing as far as possible I have not shown in detail the parts ofv a printing press, nor the numbering printing devices, and it will be understood that any nress head or cross head, which is employed to do certain printin 'upon a strip of paper with its inking r0 1, and cooperative press bed, will suit my purpose herein. My invention relates to devices for raising the cross head out of normal printing position while at the same time projecting a different printing mechanism for contact with the paper on the press bed. I

l The frame of the flat bed press is illustrated at 1, having standards 2, 2 at each side thereof, which slidably carry the cross head or printing head 3, in the'usual manner. As in the flat bed presses of normal present day type, the cross head is resiliently held downwardly on the standards by means of springs 4.

Extending through the cross head and journaled therein is a shaft 5, which is supported at each end by link arms 6, 6, of

which but one is shown, since their construction is the same on both sides of the press. These link arms are mounted over eccentric ends 7 of the shaft, and are themselves supported and operated by means of crank arms 8 located on a rocking shaft 9, that extends across beneath thepress bed.

A rocking of the shaft 5, will operate to elevate the aXis thereof with relation to the link arms, and hence elevate the position of the cross head with relation to the cross shaft 9. This will also elevate the head with relation to the bed of the press, which, as in normal construction, will bear a constant relation to the said shaft 9.

Nor normal printing devices are shown in connection with the cross head, except a diagrammatic showing of a number wheel 3*, which is the form of printing device with which my invention is of particular value. It will be understood that'whatever printing devices are employed, they will, as normally positioned in the cross head ofthe press, be held out of operation on the bed when the elevation of the head has been accomplished, as above set forth.

.It follows from this, that the partial revolution of the shaft 5 at desired intervals will throw the normal printing device, such as a numbering counter. out of printing relation with regard to paper lying on the bed of the press.

The said shaft 5 has located at the desired intervals of its length within the cross head,

eccentric portions 10, and the body of said head carries a series of plungers 11, which lie in the path of said eccentrics.

Through the center of the head, out of line with the normal printing or numbering devices, is a bar 12, which carries the de sired number of ty e bars 13, said type bars having the word i oid, or some other word denoting cancellation mounted thereon in the desired type.

The head is formed with inwardly flanged plates 14, 14, which are secured beneath the body. at 15, 15, so as to form a hollow rectangular space 16, running the length of the head. Thebar 12 has a flange 17 which slides in the hollow space, and between this flange and the fianges of the plates 14, are located the desired number of spiral springs 17 which act to keep the said bar upwardly away from printing position in the cross head. This keeping up of the bar also retains the plungers in contact with the eccentrlcs.

When the shaft 5 is rocked, however, to raise it upwardly on the link arms, as here tofore described, the plungers 11 will be forced downwardly by the eccentrics, and

- thereby force downwardly the type bars 13,

so as to place them in a position to print against the bed of the press, even though the cross head be slightly elevated.

i the gear in a like up The automatic mechanism which is preferably employed to accomplish the rocking of the shaft 5 of the cross head, will now be described. shaft, with racks to operate it, and a slide which forces up one or the other rack dependent upon its position. For locating the slide, a cam is employed which is operated by a large ratchet wheel, which is moved step by step by a mechanism under control of the shaft 9.

On the side-of the press frame is mounted a support 18 which mounts a stub shaft 19, on which are the large ratchet wheel 20 and the cam disk 21. The ratchet wheel and cam disk are journaled on the stub shaft and connected together.

The support provides a track 22, for a slide 23, which reciprocates beneath the gear 24 mounted on the shaft 5 of the press head,

The slide is open through the middle, as

at 25, and at its right hand end is provided with a pivotal connection with a lever 26. This lever is fulcrumed at 27 on the support and has as its end beyond the fulcrum a roller 28, that contacts with a relatively small nose 29 on the cam. The movement of the cam into a position where the nose contacts with the roller 28 will movethe slide through the instrumentality of the lever' for a short distance to the right.

The slide has springs 29*, which serve to keep it in its left hand position except when under control of the said cam nose.

The gear 24, ,while mounted on the eccentric 7. is formed with the shaft 5 as its center. Mounted to slide vertically in the two guides 3 on the head, are rack bars 30, 31, which mesh with the said gear. The ends of the rack bars during the movement of the head up and down, are carried along with and down movement.

The opening in the slide is not wide enough to permit the ends of both bars to move downwardly, and dependent upon the position of the slide either the right hand rack bar 30 or the left hand rack bar 31, will strike on the unslotted portion of the slide, and thus revolve the gear.

The moving of the slide to the right will cause the left hand rack bar to contact with the slide, and will revolve the gear clockwise, This revolution will move the eccentric support 7 so that its longest radius from the true center of the shaft will be downward, and will thus elevate the cross head shaft with relation to the operating links. This same clockwise movement will throw downwardly the plungers and Void type bars.

Due to the construction above described. it is only during the period when the slide is under control of the cam nose, that this It comprises a gear on the about.

The large ratchet must have the number of teeth therein corresponding to the desired number of times that the normal printing shall take place, and the cam nose must be of a dimension which will regulate the number of operations of the press head during which Void is to be printed.

In the device in autographic register paper printing, as was stated in the introductory matter hereto, there would be say five hundred and ten teeth on the large ratchet, and the cam nose would stay in contact with the slide operating lever f ten of the ratchet teeth.

The teeth 32 of the ratchet are spaced about its periphery and the ratchet controlled .against reverse movement by a spring pawl 33. Mounted to slide in a pair of brackets 34 on the side support, is a sliding bar 35, carrying-a roller 36 on its lower end, and a pair of springpawls 37 and 38 on its upper end.

The pawl 37 contacts with the ratchet, and a guard plate 39 extending tangentially of the ratchetperiphery prevents the successive contact of this pawl 37 with more than a span ofone tooth on the ratchet. The guard plate is held adjustabl 'by bolts 40 engaglng in a slot 410 f the p ate, so that if jmou nted on the side support, and has a desired a span of two or three teeth for each operation may be arranged for.

r The sliding bar 35 has a collar 42 and a coiled spring 43 hearing there-against, which retract it from contact with the ratchet, and the bar is moved toward the ratchet by] any desired contact means mounted on the-cross head operatin link.

As a typical mechanism or this purpose, is a bar 44, having a contact nose 45, for the roller 36. Thls bar is'pivotally mounted as shown, on the link, and is bent outwardly so as to clear the edge of the sidesupport.

When in normal position the arm 44 is adapted to rise each time the shaft 9 is rocked and to force over the roller 36 thereby impartinga pawl actuation to the ratchet or gear wheel 20.

The arm is guided in a bar 50which is cut out portion 51 in which the arm-44 slides and is guided. A- latch plate or abutment plate 52 is hinged at the outer end of the cut away ortion 51, and serves to fill all but a smal part of the cut when lowered and held by a hook 53 mounted on the bar 50 and engaging over a pin 54 on the plate.

When it'is desired that the arm 44 cease to operate the hook is released and the plate lifted, whereupon the arm will be free to be deflected by the roller 36 instead of press-v mg 1t outwardly and upwardly. The -'.use

of this plate thereby permits of the cancel- I beginning at the dejs e ling device being thrown permanently in or out of operation, at the desire of the operator.

The second pawl 38 on the slide bar is adapted 'for use in giving. the'ratchet an extra push at the two points when the cam nose is riding under, and riding away from the rack slide operating lever.

On the face of the large, ratchet are placed two teeth 47 and 48. The teeth are so plac that when the nose is coming, into operative position, the pawl 38 will contact with and move the tooth 47, and when the nose is movingout of operative position the pawl will contact with and movethe tooth 48.

Between the contact of the extra pawl 38 with said two teeth, the peripheral teeth of the ratchet will, time the operation of the cam.

-It shouldbe observed that the number of teeth on the face of the ratchet between teeth 47 and 48 is not the entire determining factor in the movement of the ratchet during the operation of the pawl 38, since the tooth 47 will come into the path of the pawl 38 in a few operations. The pawl 38 has a greater length of movement than the pawl 37 since it is not under control of the plate or finger 39 andwill move the teeth 47 and 48 a greater distance than the pawl 37 will move the ratchet teeth. The teeth 47 and 48 are spaced so as to cancel but four or five checks. may be applicable to the side roll which is made up of small checks, while in the neigh borhood of one thousand large checks would teeth in'the path of the extra pawl 38.

'As shown in Figure 5 the ratchet will haye fsay, one thousand teeth and these' adare set in positions (1 number of, ratchet m shifting teeth. 47 a celerate the movement ditional tooth plates teeth away from t and 48, and much of the ratchet 20. I Y 1 The teeth of the platesf55 are spaced a distance which will bring the various teeth in contact with the pawl 38 at each operation of the bar 35, and as soon-{as the pawl 38 strikes these plates the ratchet, is moved.

exclusively by the pawl 38,- onewide spaced tooth at a time. J

This in thdillustration in Figure 5, the arrangement is as -follows :-'Beg1nning to count the teeth of the ratchet from the edge of the special lateral tooth 48, 308 teeth are One thousand teeth on the ratchet tooth plates 55. in order to place additional counted off. A plate 55 is then set so that the apex of the foremost tooth thereof will be six teeth away from the 308th tooth of the ratchet. A series of plates are arranged around the ratchet, the teeth thereof being spaced to contact with the pawl 38 at each operation, until the teeth 47 are reached.

When the large ratchet has been turned step by step by the pawl '37 for 308 counts, the pawl 38 will then contact with the foremost tooth of the foremost plate 55. By count it will be noted that there are teeth on the plates 55 and the result of this will be that in 25 operations of the numbering press, the teeth 47 will be reached. The spacing I of the teeth 47 and 48 will then permit four or five cancellations to take place after which the cam will shift and the operation begin over again. In the arrangement illustrated 333 checks will be numbered between each cancellation.

Any variation of this can be accomplished by a proper positioning of the plates 55, and

the proper spacing of their teeth apart.

It is believed that the operation of the mechanism as a whole will now be apparent from the matter set forth above describing the operation of the various instrumentalities.

While'described as having particular bearing to use with a numbering machine, and a Void printing mechanism when the numbering machine is out of operation, it is not desired that my invention be limited in its scope to this special application.

Neither is it desired that reference to specific mechanism be construed as a limitation of my claims where their terminology permits of the substitution of equivalents for those set forth.
